Well the amount of gas is worse but the smell is negligable, almost a stale smell and not rotten egg smell. Now both tanks have it. What could be causing this? Where the plants are, there is no gas from the substrate, where there are no plants, right in the middle of the tanks, there is the gas. I got the MTS and they have dissapeared into the substrate, most of them anyway. The larger ones seem to be happy on top during the day and even climb to the top. Could it just be air pockets from saturated O2 in the tanks?
I was also looking at the bottle of Aquasafe and was wondering. Sodium hydroxymethane sulfinate, polyvinyl pyrollidones, organic hydrocolloids, organic chelating compounds. Chelate, could that precipitate with a dose of micros? Could anything be coming out of this solution that could cause this? I dose 1 tsp to treat 10 gallons but i am only changing 5 gallons, could I be adding too much?
Could it be nothing more than the hotter weather causing this?
